E-Cucking 

Having online sex with someone while in a relationship, knowing your partner knows of your/their escapades.

I love E-cucking my boyfriend.

He knows about all the men I get with online.

e-cucking 

When you watch 2 more people have sex online.

Due to bob's lack of skills with women he resorted to e-cucking as a replacement.
